Application September 13, 1954, Serial No. 455,461

7 Claims. (CI. 30-40) The invention relates to :a novel holder construction safety razor assembly with a ribbon blade. Whereas most of the conventional safety razors in use at the present time have single or double edged interchangeable blades, such blades have to be changed more or less frequently, the blades have to be stored separate from the safety razor, and the method of changing blades is not always convenient, nor positivelysafe. The invention herein referred to has as its object to overcome the inconveniences of many safety razors .now in general use by providing a pair of rollers for supporting the ribbon blade, the ribbon blade being attached to the rollers and Wound up one of the rollers and asplit spring metal ring which engages the periphery of the ribbon blade and helps to hold the same in place in the razor, the assembly being in accordance with the following relationship: a safety razor blade consisting of an elongated .thin and narrow ribbon of hard metal with at .least one sharp edge is attached to the novel holding device .of the present invention, said ribbon being wound on a roller; the-roller comprises a cartridge with the ribbon blade wound on same and held securely in place, the length of the ribbon blade being sufficient to provide for long use with a fresh sharp edge available at all times by rotating a roller.

The razor blade holder consists of a frame with two apertures for the rollers, two slots at right angles to the rollers for stretching the ribbon blade thereon, and one rectangular aperture in the block located above the roller apertures for'shaviug waste material, and four slots on top of the rectangular aperture to lead shaving waste material from the blade into the rectangular aperture.

The elongated ribbon blade wound around a roller is inserted into a. roller aperture of the holder and the free end of the ribbon blade is drawn out through the side slot in the holder at a right angle to the roller, and thus drawn, the ribbon blade goes around the top of 'the holder, into a slot on the opposite side of the holder and is fastened'to the end of the second, empty roller. The elongated metal-ribbon blade drawn around the head of the holder is made secure to the holder by meansof a metal frame clamp whose leg ends are flexible and provided with knobs at their ends which, when the frame clamp is completely inserted, become securely set in corresponding depressions in the holder. The metal ribbon blade is held securely in position passing within side channels in the holder and in a groove of the head of the holder, and a rib in the frame clamp to prevent side slipping. The metal ribbon blade isiprevented from unwinding off its roller by means of a brake washer pressing against the flanges of the rollers, the brake washer held by a spring and sliding bolt, a further safeguard against the unwinding of the ribbon blade is provided by a split spring ring encasing the periphery of the roller.

The handled the safety razor blade holder is constructed of two parts, hinged to the holder and folding togetherto enclose the holder when *the "razor =is "not in use, thus forming abox shielding the blade and'holder;

the handle is unfolded for use of the razor and its two parts are locked together by a concavity in one part, and a corresponding rib in the other part, as well as "by an additional slip bolt.

With the above mentioned, and other objects in view, as will become hereinafter apparent, the invention con sists in general of certain novel details of construction and of combinations of parts hereinafter fully described, illustrated in the accompanying drawings, and particularly claimed.

In particular, the following figures represent:

In the construction of the safety razor with ribbon blade two rollers 1 .and 2 (Fig. l) are provided, onone of which the flatribbon blade 3 is wound,.'said ribbon blade having at least one sharpened edge 4 (Fig. '6). Part 5 of the flat ribbon is blunt and somewhat wider than the sharpened portions of the ribbon blade which is attached to the rollers by .means of additional lead ribbons 6 and .7 (Figs. 4 and 5,). The ends of the lead ribbon are attached .to the rollers .by means of slot 8 and pin 9 (Figs. 2, 4, 5).

The free ends of the lead, permanently attached ribbons are T-shaped (Fig. 4.). The ends of the .ribbon blade are provided with appropriate apertures .10 through which they are locked onto the T-shaped .ends of the lead ribbons 6 and 7.

As shown in'Fig. 4 lead ribbon .7 for mounting ribbon blade 3 to the roller is provided with projecting tongue 51 which is narrower at the neck ofsaid tongue than the width of the slot 10 to permit the ribbon 3 and=lead 7 to be fiat in relation to each other after the tongue and slot are interengaged. Tongue 51 terminates in a widened end portion 52 which is wider than the width of slot 10 and shorter in width than the length of slot 10 to permit portion 52 to be inserted through slot '10. Lead =ribbon 6 is similarly constructed with respect to its through engagement with the other end of razor ribbon 3. At opposite attached ends,lead ribbons 6 and'7 respectively lie in flat face to face relationship to the corresponding ends of the razor ribbonfS.

As shown in Fig. 5 the insert of ribbon 7 is passed a through the opening of the open spring ring '11 and is attached to the roller'by passing theterminal end through slot 8 so as to be held therein by pin 9. The sectional iview of the roller which is shown in Fig. 4 with the ribbon blade in unlocked position provides 'a clear illus-tration of the attachment action of the pin.

The ribbon blade wound on a roller is 'heldin place by means of open spring ring 11 (Figs. 1, 2, '4, 5 The roller cartridge with "a'ribbon blade and spring ring sur- Patented May 13, 1958 .7

rounding the latter is inserted into the round opening of the holder 12 in such manner that the roller flanges 13 rest in the appropriate counterbore of the opening (Figs. 1, 2).

From the roller 1 the ribbon blade is drawn through side slot 14 in the holder, extending up along holder side channel 15, encircling the head portion of the holder, and then down side channel 16 through side slot 17, and is locked onto roller 2 by means of short blunt ribbon 7 (Figs. 1, 5, 7).

The frame clamp 18 (Figs. 1, 2, 8, 9) holds the ribbon blade to the head of the holder, and. the legs 19 of the clamp 18 cover the ribbon blade loosely in side channels and 16 (Figs. 1, 7), and keeps the ribbon blade in place.

The legs 19 of the frame clamp 18 have two knobs 20 which, when set in the depressions of the holder, keep the frame clamp 18 firmly in place; the ends of legs 19 are flexible;

On U-shaped frame clamp 18 there is also rib 21 which dips from a center bar connecting the legs 19 into an appropriate groove on the head of the holder, bends the ribbon blade slightly, and keeps said ribbon blade more firmly in place (Fig. 2 and Fig. 3 show the rib 21 bending the ribbon blade and Fig. 8 shows the details of the U-clamp). Between the roller openings there is an opening or counterbore 22 (Fig. 3) in which there is provided spring 23 and sliding bolt 24 with brake washer 25 on the end of the bolt (Figs. 1, 3). The brake washer 25 is mounted on the bolt loosely and is free to slide and turn on its axis. The spring and bolt press the brake washer 25 to the flanges of the rollers, and therefore pressing action of the washer 25 permits it to exercise its braking function to prevent the rollers from unwinding the ribbon blade.

One segment of the washer 25 is cut off, and on the opposite side there is a small depression 21:: into which pin 26 enters (Figs. 1, 3), the pin keeping the washer from turning. In this manner when pin 26 enters the depression in the washer 25 the brake action of the washer 25 is facilitated.

On the lower portion of the holder are two ribs 27 (Figs. 1, 2, 3) to which the handle parts are attached by rods 28. The handle consists of two parts 29 and 30, hinged on the rods, and when the handles are folded (Fig. 3) they form a box for the holder. Handle parts 29 and 30 are provided with bent edges 31 which lock on groove 32 of the clamp (Figs. 1, 2, 3, 8, 9).

When the handle parts are in an unfolded position, a

firm handle unit is provided by their locking through slip bolt 33 (Figs. 1, 2). There are four slots 34 in the head of the holder and through these slots: waste passes into chamber 35. Part of the head portion of the holder alongside slots 34 is provided with a conventional comb 36 (Figs. 1, 2, 7).

Through the entire head portion of the holder there is an opening 37, into which a lock is inserted (Figs. 2 and 3). The lock consists of two metal rods 38 and a spring 39 mounted on the narrowed ends of the rods. The outer ends of the rods 38 are conical shaped and under tension of spring 39 the ends of rods 38 enter into openings 40 of the ribbon blade (Fig. 6), and finally rest in depressions 41 of the frame clamp (Figs. 1, 8, 9) thus securing the sharp edge of the ribbon blade 4 (Fig. 6) on the head portions of the holder, and providing an additional safeguard against the ribbon blade rolling back in the event of its breaking.

After metal ribbon blade 3 is used up to the end, and it is necessary to replace it with a new ribbon blade cartridge, bolt 24 is pushed in the direction of washer 25 disconnecting the washer with pin 26. Washer 25 is turned on bolt 24 so that flange 13 of the roller becomes free. In this position of the washer the clamp is pulled away, metal ribbon blade 3 is unlock from blunt short ribbon of empty roller and the roller with the used rib- 4 bon blade encircled by safety ring is pushed out from its hole in the holder. A new roller cartridge is inserted in its place and the end of the new ribbon blade is locked onto the blunt ribbon of the empty roller, washer 25 is turned back toits former position and clamp 18 set in place. The safety razor is, after this replacement operation, again ready for use for a long time.

While there is herein shown and described the preferred embodiment of the invention, it is nevertheless to be understood that minor changes may be made therein without departing from the main idea and scope of the invention as claimed.
